Abstract: The cuboid coffer housing comprises a base part (12), a cover part (14), four side parts (16) and four corner parts (18). The side parts are connected with the corner parts through plug-in connection of the base side, and the corner and side parts connected together with one another are firmly connected with the base part to a bowl form. The bowl form of the cover part is detachably subjected on top edge turned away the base part. A mounting element (22) is intended on the corner of the cover part congruent with the corner part. The cuboid coffer housing comprises a base part (12), a cover part (14), four side parts (16) and four corner parts (18). The side parts are connected with the corner parts through plug-in connection of the base side, and the corner and side parts connected together with one another are firmly connected with the base part to a bowl form. The bowl form of the cover part is detachably subjected on top edge turned away the base part. A mounting element (22) is intended on the corner of the cover part congruent with the corner part. The mounting element is adjustable between a cover mounting position firmly connected with the corner part and a cover releasing position in back and forth manner. The base part is formed along its circumference edge on top side with a rotating external and internal ribs that limit a rotating base groove. The side parts and the corner parts are formed on both sides with a pluggable rib pluggable in the base groove. The corner part is screwed with the base part. The corner parts and the side parts are formed on the cover side with insertion slots and the cover part along its edges with a rotating pluggable rib. The cover part is formed on its corner with a depression that is intended for receiving a head part of the mounting element. The mounting element has a foot part connected with the head part. The cover part is equipped between the head part and the foot part. The head part of the mounting element is formed with a rotating handle rib and with a tool slot. The foot part of the mounting element is formed with a fixable key-bit and the corner side is formed with a key hole for the key-bit. The corner part adjacent at the interior side on the key hole is formed with a stop depression for the key bit. The base part is formed along a part circle uniformly distanced with holes for a brake hub of the welding wire coil. The side part is formed with a welding wire outlet hole. A welding wire-guiding element assigned to the welding wire outlet hole is equipped on the interior side. The welding wire-guiding element is formed with welding wire-guiding surfaces appositively forming in paired and rectangular manner and rejuvenating itself convex to the welding wire outlet hole and forms a quadrangular funnel. Connection sockets are equipped on the side part for an electronic device present in the coffer housing. The base part is formed on the inner side with bearing pins for a circuit board of the electronic device. A handle is secured on the side part.
